Using novel position and trading data for single-name corporate credit default swaps (CDSs), we provide evidence that CDS markets emerge as “alternative trading venues” serving a standardization and liquidity role. CDS positions and trading volume are larger for firms with bonds fragmented into many separate issues and with heterogeneous contractua...

We provide a model of nonredundant credit default swaps (CDSs), building on the observation that CDSs have lower trading costs than bonds. CDS introduction involves a trade-off: it crowds out existing demand for the bond, but improves the bond allocation by allowing long-term investors to become levered basis traders and absorb more of the bond sup...

I model an entangled financial system in which banks hedge their portfolio risks using over-the-counter (OTC) contracts. However, banks choose not to hedge counterparty risk, and thus the idiosyncratic failure of a bank can lead to a systemic run of lenders. An inefficiency arises because banks engage in a version of risk shifting through the netwo...

This paper shows how uncertainties about funding in an interwoven system of intermediation can lead to excessive liquidity hoarding. In the model, funds are channeled through several financial intermediaries (banks) until they are finally invested in real assets. In case of a funding shock, banks that are uncertain about their own loans being rolle...

This paper uses macroeconomic data to measure the consumption of active investors that are wealthy and derive a large fraction of their income from the capital they own. The resulting stochastic discount factor is tested on the time series and cross section of asset returns and yields reasonable relative risk-aversion coefficient estimates using st...

In our empirical study we examine the dynamics of the price evolution of liquid stocks after experiencing a large intra-day price change, using data from the NYSE and the NASDAQ. We find a significant reversal for both intra-day price decreases and increases. Volatility, volume and, in the case of the NYSE, the bid-ask spread, which increase sharpl...

In our empirical study, we examine the price of liquid stocks after experiencing a large intraday price change using data from the NYSE and the NASDAQ. We find significant reversal for both intraday price decreases and increases. The results are stable against varying parameters. While on the NYSE the large widening of the bid-ask spread eliminates...

In this study we examine the evolution of price, volume, and the bid-ask spread after extreme 15 minute intraday price changes on the NYSE and the NASDAQ. We find that due to strong behavioral trading there is an overreaction. Furthermore we find that volatility which increases sharply at the event decays according to a power law with an exponent o...

In and near thermal equilibrium microscopic reversibility resulting in detailed balance has specific consequences like the symmetry of time dependent cross correlation (TDCC) functions and fluctuation dissipation theorem. In this paper we study some consequences of the absence of microscopic reversibility on financial processes. By analyzing high r...

In this paper we compare market price fluctuations with the response to fundamental price drops within the Lux-Marchesi model which is able to reproduce the most important stylized facts of real market data. Major differences can be observed between the decay of spontaneous fluctuations and of changes due to external perturbations reflecting the ab...
